Application Notes
1. The transformers have been developed for use as transmit and receive
transformers in T3 or DS3 links, using bit rates of 44.736 Mbps and
B3ZS coding on coaxial cable. The characteristics allow compliance
with the pulse templates of CCITT G.703 as well as ATT T.A.34. The
transformers are also suitable for the E3 interface at 34.368 Mbps with
HDB3 coding or STS-1 applications, at 51.84 Mbps according to Bellcore
TA-NWT-000253. The LC-1 and QC-1 packages are pin-compatible with
T1-1 and T4-1 6-pin DIP packages.
2. Bandwidth specifications are typical in a 75 Ω system. Return loss
meets the requirements of G.703. Materials used in the products are
UL94-V0 recognized. Products meet the requirements of IEC 695-2-2
(Needle Flame Test).
3. The surface mount LS-1package is available with optional Tape &
Reel packaging. To order, add a “T” suffix to the part number (e.g.
PE-65967NLT).
4. The Transwitch MRT TXC-02050 chip is also designed to operate in
6.312 and 8.448 Mbps interfaces. A 1:1 transformer (PE-64934) is rec-
ommended.
